AE text looks "crunchy" after render with AME

Hi,

I've created titles in After Effects. They are text made in after effects. The titles don't move but a mask layer moves on top of them. I'm adding all screenshots of my comp and also of AME settings. Post house asked for QT Adobe ProRes 4444 with alpha channel. My comp is set up as just typed text with the mask layer that moves onto the text (so it's visible) then leaves it. No idea why my text is crunchy. I saw in another post where problems can arise when not lined up to grid which I didn't know. Do I need to have my text lined up on the grid? Included screen of that too.

Any help is appreciated.
